' My invention relates in general to door frame construction. Y

One of the objects of my invention is to provide ai metal frame for adoor lopening in such manner that it will form a mould for cement orother mortar, making a homogeneous door lframe'of very solidconstruction.

Another object is to provide a metal `trjrn Y for a concrete doorframethat will bermly anchored in place.

Another Objectis to provide a metal trim for a door frame that will inaddition to forming afmould'for the concrete serve to reinforce it. Y-

Another obj ect is to providea metal trim that will act as a guide orground to define the plane of the plaster onthe adjacent walls.

Another object is to provide improved means for mounting the hinges ofthe'door.

A. further object is to provide an improved trim construction so thatabutting members may be fastened together very'readily.

A still further object is to provide anovel support or guide for holdingthe metal trim defining the doorV openings in vplace during theconstruction fof the' wall. i

rIhere vare other objects i of my invention which, together with the'foregoing, will' be described in the detailed specification which 39 isto follow, taken in conjunction with the accompanying drawings formingla part thereof. l Y r 'Referring now to the drawings: M Fig. 1 is afront elevation of the metal trim for a door opening, `together with thesupporting braces necessary to hold it in place during construction; Y fy 1 Fig. 2 is a crosssection of one Vof the door iambs and of the baseof the support showo ing the manner in which the metal trim is held inposition by the support;

Referring now .to Figs. 1 to 9, inclusive, I shallnow.'describe-themanner in which myimproved metal trim is placed in-position during the construction of a building; -f g A board 2O isnailed to the floor vorotherwise 80 suitably attached to the roughconcrete licor ofthe building at the point at which the door opening isto be made. The brace or support is next placed in position on topl ofboard 20 and nailed as at 20.` This support21 com# B5 prises two uprightboards 22 and 23 suitably spaced apart and fastened togetherby nailing aseries of wooden blocks 24 between the two uprights 22 and 23. yAt theupper portion of the supporting member 21, a suitable spacing member 2 5'is attached in position.

A bracket 26 is fastened to the spacing mem-V ber 25. The bracket 26contains an opening to receive the sleeve 27. The externalV surface ofthe tubular sleeve 27 is suitably 95` threaded and the nut 28`isthreaded on the sleeve and is supported bythe bracket 26. rlhe sleeve 27has a'cam 29 of a construction for suitably binding to a pipe or tubularextension 30 with it. The pipe 30 is adapted 1100 tion.

to be slipped through the sleeve until it en-V gages the ceiling. Thecam 29 is then operated to lock the pipe in its extended posi- The nut28 is then turnedso thatthe support 21 is maintained firmly in positionY by being forced downwardly and the pipe 30 upwardly between the floorand the. ceiling. A bracket 31 is attached to the spacing block 25 thathas an opening for receiving the pipe BOthus acting as a guide andsupport for it.

The spacing member 25 is employed Vsoftha't Y thesupport or pipe 30 willnot interfere withV f iixed to each ofthe boards 22 Vand 23.

the construction of the wall'a'nd partition above the door. The support21 just described is adapted to hold one side ofthe metalQfr-ame in itsproper position, another supportl` similar to the support 21 holds theother side of the metal frame in position in the same manner as will nowbe described.

The lower end of the support 21 carries two connecting membersor devicessuitably af- These connecting members consist essentially of a tubularsocket 34 that is adapted to receive a clamping bolt 35.y The clampingbolt V35 has a projection 36 thereon that is adaptedto lit over themetalk flanges 37 'of the ,door frame. and hold 'it' firmly: in placelwhen the nuts, Vsuch as 38, are tightened. A similarr holding bracketis mounted atthe top of. the

Y support .21, as is designated in Fig. 1 by the numeral 40. Y n

The surfaces of the door framenconsistessentia'lly of light metal havinga channel shape withextending' sides.Y Thisvv metal frame Vis shaped asshown-in Figs. 4 and 9, wherein 4the numeral 41 designatesthje metalframe; Thek sides 42V and 43 off the metal frame lare bent outwardly at43 and then back vonfthemselrves Ythus doubling up the metal as 'shownat 44v and 45. The rear por-` tions-46and 47 extendinwardly on anincline andparallel f to the surfaces 44 and 45 of the extension.Theextreme edges terminate 45 into a hooked'shape, 48 andzr49. Theinclined sur-faces 46. and 47 serve toform a 'bond for :the plaster,preventing the plaster from coming away fronithe block partition.

Theghookedportions 48.y and 49 provide an effective key forliol'ding theanchors on' to prevent the metal' frein-pulling awayfrom the cementfill. The extensions 44 and 45 deine thewall surfaces and thereforeserve as guides or are usuallytermed as, grounds for plastics. Y n

Each member of the door framev is formed v insubstantially thel samemanner', that is to ysay,g.the two Vsides andthe. top. The two Vsides41j, 41, andthe tcp j amb 41.y The top jamb 41 is cutaway ateach end toabut ,Y the sides- 4l and 41.

jamb members 41, 41 to extend through the slots. The portion v54 is thenbent over as shown in dotted line at 55to clinch the side and topmemberstogether.` A

' Suitable recesses 58 are formed in the metal of the member 4l as maybe seen in Fig. 6. The edges 59 of the recess 5 8y are bent under sothat when the hinges are placed in position, these edges willbe suitablycovered. A wooden block V60 is suitably placed behind these recessesandl temporarily held in any suitable `manner vuntil the frame formed byi VtheV members 41, 41 is filled Iwith a suitable are Vmade from hollowtileor gypsum blocln In order to anchor thedoo'r .frame into the wallsuitable anchors, preferably of the shape shown in Fig. 9' numberedGlare provided. These anchorsfl are provided. with forward and. rearwardextensions and are. usually made of metal with suitable. opening-s1therethrough to form key spaces-for mortar. The rearward extensions.are4 adaptedtov be held between kjoints of the gypsum'. or tileY -block.

The forward extension is 'provided with openings to. form key spacesforbijnding theV anchor in to the cement mortar.- EachA side of theanchor 61 is provided'withctwo' prongs 62 and 63. the hooked portions 48and 49 of the door The prongs 62' and G3. act to holdframe and topreventthe'sides fromspreading when the form is filled' with mortar orconicrete. The :prongs suchi as 64 are bent atan angle, in this caseupwardly so as. to bind on the edgesy 46 and 47 of the door frame. whenthe anchoring ymembersl are temporarily placed after the door openingmembers -have been placed in position. v The anchors suchas `61 areplacedbetween each joint of the blocks forming the parti-tonsandthe twosides andv top of' the door opening; Now when the form is filled withconcrete,l the, metal trim defining 'the door yopening is firmly lockedto the walls. 1 In this manner; a

unitary structure` is obtained which: isVV in reality a concrete doorVJambhaving a light y metal covering. Since light metal is employed, theface of the door frame may be made in any pattern and yet whenthe mortaris poured in, thewhole becomes an. integral construction. Theprojectio'nsfsu'ch as 44 and 45, the` forwardly inclined flanges 46 and47gtogether with the hooked edges 48 and 49 combine to form a key forthe plaster so that it isV anchored rmly` when placed in position. Sincethe whole construction forms a unitary door opening, there is no dangerof the plaster cracking. This is illustrated very well inFigf4. Thereference numeral 65 designates the tile or gypsum block forming thepartition, While 66 designates the plaster when in position. The mannerin which the plaster is keyed tothe hooked edges can be readily seen. Ananchor lhas been shown in position and the manner in whichthe concretedesignated by the reference numeral 67 takes the forni of the door frame41 will be obvious. The operation'o'f the anchor in forming the'wholeinto a unitary mass can also befvery well seen from this view. It willbe appreciated that this construction is such that there is nolikelihood of the plaster cracking onv either sideof y the door framesince no vibration is possible by this construction. vSince the edges ofthe member 41 are bent back upon themselves at 44 and 45, they areconsiderably reinforced atthese points. Inaddition, since thin metal isemployed,a sharp edge is formed where they turn back and this preventsany cracking of theplaster at this point, which would be present if arather rounded surface were formed. vIt will be appreciated that thisform of construction fora door opening is very `easily manufactured andVcan be set in place with a great deal of facility so that the resultantstructure is not only greatly lsuperior but is cheaper.

It will be understoochof course, that the support 21 supporting each ofthe vertical ICG door members 41 and 41 are removed as soon These edgesare then nailed to the wood studs 71. y It will be seen that the woodstuds 71 project inwardly and are enclosed, at least to some extent, themetal frame 41. The form is Vfilled in with cement the saine as beforegiving a unitary construction. The forwardly extending iianges suoli. as72, form akey or anchor for the plaster 73 in a niainer similar to thatalready described. It will thus be seen that the benefits of inyimproved v construction can be'obtained with this form of partitionalso'. Fig. 11 shows the manner in which the vmetal trim may be appliedto an ordinary 2 wooden window to give it the samefinish as the doorvframe. VThe' metaltrim member as shown at 7 5 may be suitably held inplace by a moulding 76 and is suitably nailed at lits other edge to ablock 77. The edge is bent back on itself to forma key-way in the same Ymanner as before for plaster such as 79.

It will thus be seen that I have provided r door frame that not only hasa pleasing appearance but one that can bereadily placed in position andwhen placed in position forms a unitary part of the partition. Themanner` of construction is suchthat it materially redunes the cost ofthe buildingand facilitates the construction; y y While I have showncertainspeciiic eins bodiments in my invention, it will beunder-f stoodthat I am awaretliatmany changes, modifications and deviations maybemade and that I desire to protect by `Letters Patent all suchchanges,modifications and deviation as come within the scope of theappended claims. l Y' i I claim: 1 a
